A method and system for transient loss reduction of a unit in combination with intercooling circulating water and heat storage
By collecting operating parameters in real time and calculating energy consumption deviations, the flow rate of circulating water pumps and the start-up of thermal storage devices are prioritized to generate feedforward correction for coal feeding. This solves the problem of insufficient cascade coordinated control between circulating water pumps and thermal storage devices in coal-fired power generating units, realizes energy consumption suppression over a wide time scale and matching of fuel supply and steam output, and improves unit regulation efficiency and equipment economy.

AI Technical Summary
In the regulation and control of coal-fired power generating units, the cascade coordinated control capability of circulating water pumps and thermal storage devices is insufficient, which cannot effectively suppress transient additional energy consumption and fuel feedforward correction over a wide time scale, resulting in a lack of coordination between energy and material flow.
By collecting operating parameters in real time, calculating the uncontrollable thermal energy consumption deviation and energy quality loss adjustment power deviation, prioritizing the adjustment of the flow rate of the adjustable flow circulating water pump, and combining the energy deviation processing of the intercooled thermal storage device, a coal feedforward correction amount is generated and superimposed on the fuel main control command to achieve cascade collaborative control.
It improved the regulation efficiency of coal-fired units, optimized equipment economy and operational adaptability, reduced transient additional energy consumption, and reduced the problem of mismatch between fuel supply and steam output.
